2007+ Mazda5 Horn Upgrade - Multiple Pics - 56k connection beware

Finally got around to replacing that wimpy sounding "meep meep" horn with dual horns. The horns I used were 135db models. I used a low tone horn and a high tone horn. I got the horns from carparts.com for $16.00 for the two horns (contrary to my writeup below that says $31 as the $31 was for 4 horns). The 3 wire tap I got from Radio Shack for $3.99 for a 10 pack. The wire I got from Radio Shack a while ago.

I elected to remove the front bumper to do the horns. It is remotely possible that you could do this without removing the bumper, but you would have a heck of a time working from the ground looking up into the tight space that these horns occupy.

The car in the writeup is my 2009 Sport. Let me know if you have any questions or comments. In total, with taking all the photos and working slow and deliberate, it took me about 2 hours to do this. Without having to take the pics, it probably would have taken an hour or so.

EDIT - Forgot to mention, these horns are LOUD. Much louder than stock. They also have a deeper tone that sounds great and not at all like the "meep meep" sound that comes from the single stock horn

Reason: forgot to comment on the sound of the new horns

Wow, that is a lot just for horns, but thanks for share,
should we need to remove the bumper for something else.

Keep in mind folks, that the horns are one wire hook up and
if you want, you can add to the stock ones in place, more
horns = more sound.

Also you can relocate the horns (Stock or after market ones)
to a different location on the vehicle, like one front and one rear,
or one on each side up front. Because you can ground them to
anyplace, just need to run the hot wire to the horn.

Trust me, its easier to just remove the bumper. The only other option is to remove the front driver side wheel, remove the wheel well liner and go at it that way. Even with that you will be working in very tight confines and it will be hard to see and hard to get wrenches etc... in there. With a lift it might be a litter easier than without but space and craning your neck upward to work on the horns would kill me as I have neck injuries.

If you can use a screwdriver, the bumper is off in 20 minutes tops.-- 10 if you've done it before... The whole project would not take more than 1-2 hours...

To me the horn is a safety device (and therefore VERY important) and in my opinion the one that Mazda gave us is not loud enough and its tone makes other drivers not take it as seriously. Can't tell you how many times I have had to use my horn in my Mazda5 and how other drivers just do not seem to react to it. My Mazda3 was even worse before I did the horns on it.

In the past few months I got pushed out my own lane twice by distracted drivers who first didn't notice my car and then couldn't hear my desperate honking. I am a defensive driver and I always stay out of other cars' blind spots, but these two cars kept moving towards me even AFTER I honked for 3+ seconds. Luckily I was able to swerve to avoid the impact without hitting another car, but the horn was definitely a disappointment. The question for me is if I should do this myself or get an auto mechanic do it. It looks like a lot of work. Considering the fact that the HID installation took me 3+ hours, how long do you think this will take me?
